Abstract
Abstract @ A system for defining graphic patterns for an NC apparatus includes: a display (102); a display control (103) for controlling the display to display, as head items, addresses comprising the designation of a straight line or an arc for a planar graphic pattern, the coordinates of an ending point of the graphic pattern, a vector angle of the straight line or a radius of the arc, vector components of the straight line or coordinates of the center of the arc, and modifiers; data setting means (104) for setting known data by successively or appropriately using addresses displayed on the display means and indicative of the straight line and the arc derived from the planar graphic pattern; a memory (106) for storing the addresses, the data set by the data setting means, and formulas; computing means (107) for computing the set data stored in the memory (106) according to the formulas to determine the addresses of unknown data which have not been given numerical values by the data setting means; central processing means (105) for controlling the computing means and the memory to store the results of computation effected by the computing means; and output control means responsive to the set data and computed data stored in the memory for controlling the movement of a machine tool.
